CAPTURING AND SUPPRESSION OF DUST FROM THE CRUSHING-RELOADING (DPP) POINT AT THE "MURUNTOG" MINE

Abstract

Detailing and suppression (aspiration) of dust from the crushing and reloading (DPP) point, design features, and promising developments are presented. Bunkers, feeders, and crushers are the most important parts of the crushing and reloading point. The amount of dust, dust size, and dust velocity in the crushing and reloading point bunker are directly related to the state of the environment. When dump trucks empty the bunker rock, dust is released and damages the environment, taking this into account, dust suppression pipes are installed along the bunker and feeder, water nozzles are installed in the pipes, and options for covering the bunker and feeder are provided. Options for determining the amount of dust on the bunker and feeder by weight, as well as the installation of closed spraying equipment in the dust formation zone, are presented.
